Who Do You Think You Are?
9pm, BBC One
This popular long-running genealogy series has a way of making you count your blessings: one thing that’s usually evident is how few generations most of us are from grinding poverty. That’s true of this week’s adventurer into the past, former Spice Girl Melanie Chisholm, whose Liverpudlian family’s journey involves a workhouse, incredibly bleak manual work and a hasty flight from the great Irish famine of the 19th century. She is also fascinated to learn that her fourth great-grandfather was a campaigner for improving working men’s lives and rights. Phil Harrison
